Dual-purpose storage bag

ABSTRACT

A dual-purpose storage bag includes a first bag body and a second bag body that share a common bottom surface and connect to each other in opposite directions, and the first bag body is formed by a mesh fabric, and the second bag body is formed by a woven fabric with a covering function and concealed and stored at the bottom of the first bag body. After being unfolded from the bottom of the first bag body, the second bag body can be folded in an opposite direction and wrapped around and combined with the first bag body to cover the objects contained in the first bag body, so as to achieve the effect of protecting personal privacy.

FIELD OF THE INVENTION

The present invention relates to a dual-purpose storage bag, and more particularly to the dual-purpose storage bag with two bag bodies that share a common bottom surface and connect to each other in opposite directions, and the second bag body can be concealed and stored or unfolded, and then wrapped around the first bag body, so that users can selectively use the storage bag as a beach bag with a ventilation function or as a shopping bag with the function of covering the objects contained in the shopping bag to protect personal privacy.

BACKGROUND OF THE INVENTION

Present existing beach bags are usually made of a mesh fabric which is woven into a bag body, so that when the beach bag is used on shores or beaches, the beach bag is breathable and allows air to pass through the hollow meshes of the mesh fabric, and the moisture inside the bag body can be ventilated. Towels, swimsuits and other items contained in the beach bag will not produce peculiar smells due to the heat, humidity, and unbreathable characteristic of the bag. In addition, most people will use an opaque shopping bag to carry various items in order to keep personal privacy and hide the shape of the items, and this kind of shopping bag usually has a bag body made of a woven or plastic fabric.

The aforementioned beach bag needs meshes for ventilation, and the shopping bag needs to conceal the objects contained in the bag body, and thus the beach bag and the shopping bag are bag bodies with completely different purposes. If the beach bag is used for shopping or carrying objects, the objects contained in the beach bag will be seen by others without any personal privacy at all. If the shopping bag is used to carry objects on seaside, the shopping bag without the ventilation function may produce peculiar smells due to the heat and humidity acted on the objects contained in the bag. Obviously, such application is inappropriate and inconvenient. Therefore, users must choose to carry a beach bag or a shopping bag according to the occasion of use and cannot use a dual-purpose storage bag with both functions of the beach bag and the shopping bag.

Surveys indicate that there are many kinds of bags with an expansion function on the market. In a related prior art such as U.S. Pat. No. 7,900,757, a secondary bag is detachably combined to the bottom of a primary bag body, so that a secondary bag can be used to protect personal privacy or to expand the volume of the bag, but the disadvantage of this patent is that the combination of the primary and secondary bags is inconvenient.

In U.S. Pat. No. 9,254,022, a secondary bag is folded and stored at the bottom of a primary bag, and after the secondary bag is unfolded, the capacity of the whole bag can be expanded, but this design cannot have both functions of a beach bag and a shopping bag for covering the objects contained in the bag at the same time.

In related prior arts such as U.S. Pat. Nos. 7,628,187, 8,156,974, and 9,271,553, the functions and structural designs are similar to those of U.S. Pat. Nos. 7,900,757, and 9,254,022 which cannot meet the requirement of using the storage bag for the functions of both of the beach bag and the shopping bag.

In view of the aforementioned problems, the inventor of the present invention based on years of experience in the related industry to conduct extensive research and experiment, and finally developed a dual-purpose storage bag to improve over the conventional bag that cannot be used for the purposes of both of the beach bag and the shopping bag.

SUMMARY OF THE INVENTION

Specifically, the present invention relates to a dual-purpose storage bag including a first bag body made of a mesh fabric and a second bag body made of a woven fabric with a covering function, wherein the first bag body and the second bag body share a common bottom surface and connect to each other, and the second bag body can be folded and stored at the bottom of the first bag body, characterized in that:

The first bag body has a pocket facing upward, and the second bag body has a pocket facing downward and connects to the first bag body in an opposite direction; and after the second bag body is unfolded from the bottom of the first bag body, the second bag body can be wrapped around the first bag body from bottom to top, and the upper edge of the pocket of the first bag body and the inner side of the pocket of the second bag body are combined with each other by a first zipper, such that the woven fabric of the second bag body is fixed and wrapped around the mesh fabric of the first bag body to cover the objects contained in the first bag body and protect personal privacy.

By the aforementioned structure, the present invention can store the second bag body at the bottom of the first bag body, and the first bag body is made of a mesh fabric and suitable to be used as a beach bag. Alternatively, the second bag body can be taken out and unfolded from the bottom of the first bag body the bottom and then upwardly folded and wrapped around the first bag body, and the upper edge of the pocket of the first bag body and the inner side of the pocket of the second bag body are combined with each other by the first zipper, such that the second bag body made of the woven fabric can cover the objects contained in the first bag body to achieve the effect of protecting privacy, and the second bag is suitable to be used as a shopping bag.
